Purpose
Examine the level of erosion in root dentin caused by different irrigation methods and protocols.
Methods
Thirty-five extracted upper molar teeth were instrumented and divided into 7 groups to undergo treatment by different methods: negative control, GentleWave® System and syringe needle irrigation following different protocols.
Conclusions
NaOCl followed by final EDTA irrigation performed either by syringe needle or the GentleWave System caused minimal dentin erosion.
